- Review all license headers. 
  Based on the generate-license-list it can be easily done through the 
  review of the license-no-license-header file:

    cat license-no-license-header | while read file ; \
            do (echo "$file"; head -20 $file ) | less; \
    done

- Sources of the plugins have been restored from the 2.2 packages since those
  were exclusively released under the GPL

- Although initially released under the GPL, I  have removed the files which fit
  this regular expression:
  egrep -i "#.*(C).*Tenable Network Security" * 
    NOTE: Except if the plugin said it was *based* on something (C) Tenable"
  grep -i  "script_copyright.*Tenable.*" *

- All the files which include non-free plugins (.inc files) have also been removed
